The aim is to improve the viewing quality of the product and to improve the skills of the developer. During code, inspection can be found and eliminated problems such as errors in the format string, race condition, memory leaks and buffer overflows, which improves the safety of a software product. People may have a different approach to problem solving. Depending on their own experience, knowledge and skills to use different algorithms, data structures, approaches to lock patterns. If these approaches are not synchronized with each other, even in a small team, a complete solution will be a patchwork of approaches, patterns, structures. The review identifies a similar inconsistency and opens a dialogue on bringing code to a more homogeneous form.
